> Verbs cannot be used to configure newly introduced miniCQE formats for
> Flow Tag and L3/L4 Header compression. Support for these formats has been
> added to the DevX configuration only. And the RX queue descriptor has been
> updated with the CQE compression format information only as well. But the
> datapath relies on this info no matter which method is used for Rx queues
> configuration. Set proper CQE compression format information in the Verbs
> configuration to fix the miniCQE parsing logic.
